You trust Wikipedia??????????????????  Even their first sentence is
wrong.  One of the things which most surprised Bill Paley was that
CBS/Columbia had NOTHING TO PATENT OR LICENSE!!  33 1/3 RPM?  Done since
1925.  12-inch disc?  Done since 1902.  10-inch disc?  Done since 1901. 
Microgroove?  Bell Labs did tests for Victor in 1926 and Edison produced
it commercially in 1927.  The name "Long Playing"  Edison again.  The
ONLY thing they had was a trademark of a capitol L and small p =  "Lp". 
Everyone else could use LP, but Columbia had the exclusive use of Lp.  


David Sarnoff had the last laugh AGAIN.  There was nothing for CBS to
have him accept or license!


The rest is pretty much OK except styrene was not used very early. 
Probably the first ones were in the mid-50s, but they seem to hint they
were used very early.  Like in 1949.


As for the one record they mention, there was a whole bunch of records
released at the exact same time, and there had been samples available in
February.

 March 31, 1949 was the kick-off day. according to this site:
 http://www.history-of-rock.com/fortyfive_birth.htm
 
 However Wikipedia says:
 Unwilling to accept and license Columbia's system, in February 1949 RCA
 Victor, in cooperation of its parent, the Radio Corporation of America,
 released the first 45 rpm single, 7 inches in diameter with a large
center
 hole. The 45 rpm player included a changing mechanism that allowed
multiple
 disks to be stacked, much as a conventional changer handled 78s. The
short
 playing time of a single 45 rpm side meant that long works, such as
 symphonies, had to be released on multiple 45s instead of a single LP,
but
 RCA claimed that the new high-speed changer rendered side breaks so
brief
 as to be inaudible or inconsequential. Early 45 rpm records were made
from
 either vinyl or polystyrene
<http://en.wikipedia.org/wiki/Polystyrene>.[34]
 <http://en.wikipedia.org/wiki/Gramophone_record#cite_note-35> They had
a
 playing time of eight minutes.[35]

 So On March 31, 1949, RCA Victor released "Texarkana Baby" b/w "Bouquet
of
 Roses" by Eddy Arnold.
